In the Green Frog Version of the 10th anniversary of the California State Railroad Museum from 1991, there are a big parade of Steam specials including Union Pacific 844 & Challenger 3985 with 4-6-0 number 1243 sitting on a flatbed Double-heading from Cheyenne Wyoming to Sacramento via Sherman Hill, Weber & Echo Canyons, the Great Salt Lake, Silver Zone Pass, & the scenic Feather River Canyon. Not only that, but during the layover in Salt Lake City, 3985 operated a 2-day round trip to McCammon Idaho & return. While 844 & 3985 are the main stars of this recently turned 35 year old event, a pair of Southern Pacific Steam Locomotives also appeared as well: Newly Restored 4-6-2 number 2472, & 4-8-4 4449 which the narrator mistakenly called the daylight number 4429 while the 2 engines are on a special double-header from Sacramento to Oakland. Other producers were also on the Railfair 1991 trips: Berkshire Productions, Lasting Impressions, Gandy Dancer Productions, Kaw Valley Films, Pentrex, the late Greg Scholl Video Productions, Dave Goodheart Productions, Skyfire Video, Revelation Video, Penn Cal Video, & Dan Engstrom of C. Vision Productions. Some of these scenes (mostly on 844 & 3985) was later used in the 1996 video: Steam Giants Across America.
